I love the Narnia chronicles and try to re-read my set at least once a year.

Last year while I was in Germany I started reading his Space trilogy, but with one thing and another I got about halfway through Out of the Silent Planet and then for some reason never picked it up again. But the next time I get a craving for sci-fi I will.

Out of the Silent Planet took me awhile to read because it was so detialed but I liked it... So many detials though. If they ever make a movie with that book oh buy would it be destoryed cause its like reading a science book only way more interesting.

I like "Narnia" very much. The second book is my favourite.
I love also one his book called Screwtipe's Letters" or something like that. It was about the battle between God and Devil in the soul of a human... interesting, really.

Ahhh, "Scretipes Letters" rullz! This book is one of his best. And "Chronicles of Narnia".... This series is classic in the Children litterature! Az "Harry Potter" and "Ronia the Robbers Daughter", as "Pooh" and "Alice in Wonderland"!

The space trilogy is one of the weirdest trilogies out there. It is a trilogy, technically, but the only things linking the books are a few overlapping characters and some overarching themes. The three books are wildly different stylistically:

Out of the Silent Planet (Mars) is a pretty straightforward Earthlings-on-a-distant-planet story with a healthy dose of Christological metaphor.

Perelandra (Venus) is hardly an adventure story at all. It's far more allegorical in nature, with a small cast of characters, and really is a meditation on the Book of Genesis.

That Hideous Strength (Earth) is perhaps best classified as a spiritual thriller, with a strange but compelling Arthurian element. Can also be read as a statement by Lewis on contemporary civilization.

It's a fantastic trilogy, but it's easy to see why some people would like one or two books but not the third, or vice versa. I don't know of any other science fiction with such a theological bent.

..and if I remember right, the space books were also meant to be a not-too-subtle dig at HG Wells too.... I read the first, quite enjoyed it, but have to be honest and say that I found the next hard going and I don't think I finished them.

Of all of Lewis's novels, Perelandra is the most consistently "Christian." It's primarily an allegory about the Garden of Eden (only set on another planet). It contains long stretches of meditations on theological topics. As a Christian myself, I think it's wonderful stuff. But I think that if I didn't know much about Christian theology I would find the book boring and impenetrable.

By the way, you don't need to have read Perelandra in order to try the third book, That Hideous Strength, which is a thriller with a much broader cast of characters and a faster plot.
